A-3.34-µc point charge and a 6.68-µc point charge are a distance l apart. where should a third point charge be placed so that the electric force on that third charge is zero? (hint: solve this problem by first placing the -3.34-µc point charge at the origin and place the 6.68-µc point charge at x = −l.) solve in complete answer for l

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
